LUMINESCENT GLASS ELEMENT, PRODUCING METHOD THEREOF AND LUMINESCING METHOD

摘要

A luminescent glass element (10) comprising a luminescent glass substrate (13) on the surface of which a metal layer (14) is positioned. The metal layer (14) is provided with a metal microstructure. The luminescent glass substrate (13) has composite oxides represented as the following formula: aM 2 O·bY 2 O 3 ·cSiO 2 ·dCe 2 O 3 , wherein M represents alkali metal element, a, b, c and d are, by mol part, 25-60, 1-30, 20-70 and 0.001-10 respectively. A method for producing the luminescent glass element (10) is also provided together with a method for rendering same luminescing. The metal layer (14) is positioned on the luminescent glass substrate (13), thereby improving luminescence efficiency of the luminescent glass substrate (13). The luminescent glass element (10) can be used in luminescent devices with ultrahigh brightness or high-speed operation.
